San Diego Mayor and former Democratic Congressman Bob Filner is resisting mounting calls for his resignation over sexual harassment claims, including one this week that he forcibly kissed two women.

“I’m not going to resign, and here’s why,” Filner said in a statement. “I do not believe I am guilty of sexual harassment, and I believe a full presentation of the facts will vindicate me.”

Filner’s statement was released just before former councilwoman Donna Frye, who brought the harassment allegations to public attention last week, held a press conference detailing some of the harassment claims made against the mayor.

Frye read aloud from the accounts of two women, one of which detailed Filner’s “extremely unwelcome” comments and physical conduct. The second woman, a volunteer for Filner’s campaign, said he “grabbed and kissed her, jamming his tongue down her throat” and later “had his hand on the inside of her bra,” Frye read.

Filner later told San Diego television station KUSI that he is “a hugger of both men and women,” responding to these specific harassment claims. He added that the “anonymous kinds of charges” must end.

“There’s been no formal complaints. There’s been no charges in a fair way that I can deal with,” Filner said.

These new details emerged amid growing calls for Filner’s resignation.

“The mayor’s lack of understanding of the debilitating effects of sexual harassment, intimidation, and bullying is an affront to all,” Rep. Susan Davis (D-Calif.) told the San Diego Union Tribune. “His behavior, if not illegal, is reprehensible.”

Rep. Scott Peters (D-Calif.) joined Davis in asking Filner to step down, saying he “will be unable to give the job the full attention it requires, nor will he have the credibility required.”

Filner’s ex-fiancee Bronwyn Ingram, who broke off their engagement last week, also released a statement to KPBS on Sunday saying Filner had displayed “aggressive” behavior and “recently began texting other women sexually explicit messages.”

“The mayor’s office is now paralyzed, engaging only in defensive posturing and struggling to survive,” Ingram said, explaining why Filner should resign. “The work of the people and for the people has ceased.”

Fifty-nine percent of San Diego residents think Filner should resign, according to a SurveyUSA poll out Friday.
